I have a Samsung Galaxy Ace, with quad-band I believe. It is possible to see the current connection network type, e.g. UMTS, EDGE, etc, by going to Settings -> About Phone -> Status. But it does not tell which frequency band it is on. Is it possible to find out which frequency band (either exactly, or just which of the four major bands) that I am using?

Based on avirk's hint, I found a way. First press the code *#0011#

GSM example:

GSM900: IDLE
T: 10, B: 10
Rx Pwr: -94, Rx ual: -
Rx Lev: 21, Tx Lev: 0-
Speech VER: AMR EFR FR
VOC: AdaptiveRate
TS: 0
Temp: 68 Batt: 71 LNA: 0
Service: Available

It is obvious that it's using 900MHz band, from the "GSM900".

UMTS WCDMA example:

WCDMA: Idle
Rx CH: 10612, R: -94
Tx CH: 9662, Tx Pwr: -
EdIo: -6, RSCP: -98
SpeechVER: AMR EFR FR
RF: Sleep2
L1: PCH_Sleep
Drx cycle: 64, PSC: 392
Temp: 67 Batt: 69 LNA: 0
Service: Available

UMTS can use two different physical layers (low level radio) UMTS-FDD and UMTS-TDD. Android just shows WCDMA, which I think is the same as UMTS-FDD, but perhaps it can refer to both of them. By looking up the channel number here you can tell the frequency bands and whether it is UMTS-FDD or UMTS-TDD.

In the above example it is using UMTS-FDD, the down-link channel (Rx) is in the 2100MHz band and the up-link channel (Tx) is in the 1900MHz band.

You can try dialing

*#*#4636#*#*

and then going to "Phone Information".

enter image description here

That will show details about the network like cell tower ID and network type. As you can see from the below screenshot, it shows "EDGE" mode :-

Also, this may only work on stock Android builds.

Not working on my Galaxy S.. –  Sachin Shekhar May 29 '12 at 14:52
    
You've missed the * on both sides.. –  Sachin Shekhar May 29 '12 at 14:58
    
BTW, there's no info about frequency band even there... –  Sachin Shekhar May 29 '12 at 14:58
    
Edited and made corrections to the code.. try it now, @SachinShekhar ; afaik, It works on all ROMs –  Power-Inside May 30 '12 at 8:36
    
Yes, it works, but not without * on both sides.. –  Sachin Shekhar May 30 '12 at 9:46

May be this XDA developer forum thread can help you to sort out the problem. The instructions are for Galaxy nexus S but may be it worth to check out it for your model.
